Retrograde fraction stratifies the degree of aortic regurgitation (AR) in patients with aortic valve disease. The purpose of this study was to develop 4D flow based voxel-by-voxel regional analysis of forward flow, reverse flow, and retrograde fraction with full volumetric coverage of the aorta. In a study with 10 subjects (5 healthy controls, 5 patients with AR), reverse flow and retrograde fraction maps were used to systematically analyze regional flow patterns and assess differences between standard (plane-wise) and voxel-by-voxel quantification of AR.
